The 1200 GC/MS system should be installed on a clean, flat surface. The minimum bench
space required for the system is 57 cm x 195 cm, for the CP-3800 GC, 1200 MS, and PC:
275 cm if the printer is on the bench as illustrated above. Ensure that the bench is capable of
supporting the weight of the system: at least 150 kg plus allowances for any options.
The foreline pump plugs directly into the MS and should be positioned on the floor beneath the
workbench on which the 1200 MS system sits. There is a 48 in. (1.2m) vacuum line from the
rear of the MS that connects to the foreline pump. To accommodate the pump, the workbench
should be no higher than 36 in. (91 cm). If you use a higher bench, be sure to place a
vibrationally-isolated table or stand under the bench to elevate the pump. The table must be
capable of supporting the 25 kg pump.
If your bench adjoins a wall, you will need to drill a 1.5 in. (3.8 cm) diameter hole through the
rear of the bench to accommodate the vacuum hose.
The PC can be positioned either alongside the GC/MS, or on a separate table. If a separate
table is chosen, it should be positioned within 10 ft (3m) of the rear of the 1200.
NOTE: See Appendix 1 for exact module specifications.
Power Requirements 1200 GC/MS
The 1200 GC/MS system requires one dedicated duplex single-phase power source with earth
grounds hard-wired to the main power panel ground for the gas chromatograph, and a fourplex
power source for the mass spectrometer, computer, and monitor. If you have additional sample
preparation devices or test equipment, we recommend a separate dedicated power source for
their operation. Never plug the mass spectrometer and the chromatograph into the same power
source, or you may overload the power source. Never use the free outlet on any of the power
sources for equipment drawing more than 2A.
Within North America these power sources must be 20A, 100-115 Vac 60 Hz
±
3 Hz.
Outside North America, power sources must be 10A, 200-240 Vac, 50 Hz
±
3 Hz.

NOTE: See Appendix 2 for complete current supply requirements for the standard modules.
The power cable from the GC is approximately 2 meters (80 in.) long and fitted with National
Electronics Manufacturers Association (NEMA) 5-20P power plugs. The NEMA 5-20P power
plug and corresponding outlet are shown in Appendix 3 Figure 5(a). NEMA 5-20P plugs are
rated at 20A and 120 Vac.
The power cable from the mass spectrometer is approximately 8 ft (2.5m) long and fitted with
National Electronics Manufacturers Association (NEMA) 5-15P power plugs. The NEMA 5-15P
power plug and corresponding outlet are shown in Appendix 3 Figure 5(b). NEMA 5-15P plugs
are rated at 15A and 120 Vac. The power cables for the computer, monitor, and printer are
approximately 7 ft (2m) long. They are fitted with NEMA 5-15P plugs.
Systems shipped outside the United States and Canada are fitted with CEE 7/7 plugs which are
rated at 16A and 230 Vac. The CEE 7/7 plug and outlet are shown in Appendix 3 Figure 5(c).
